~> Xcode 8

This problem occurs when command line tools are installed after Xcode is installed. What happens is the Xcode-select developer directory gets pointed to /Library/Developer/CommandLineTools.

Step 1:

Point Xcode-select to the correct Xcode Developer directory with the command:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Step 2:

Confirm the license agreement with the command:

xcodebuild -license

This will prompt you to read through the license agreement. 

Enter agree to accept the terms.

>= Xcode 8

Step 1:

As Bruce said, this happens when Qt tries to find xcrun when it should be looking for xcodebuild.

Open the file:

Qt_install_folder/5.7/clang_64/mkspecs/features/mac/default_pre.prf

Step 2:

Replace:

isEmpty($$list($$system("/usr/bin/xcrun -find xcrun 2>/dev/null"))))

With:

isEmpty($$list($$system("/usr/bin/xcrun -find xcodebuild 2>/dev/null")))
